Prevalence and Antimicrobial Susceptibility of Ureaplasma urealyticum and Mycoplasma hominis in Female Outpatients, 2017 - 2021 by Lu-Qing Zheng, Qing-Yong Wang

Background: The latest region-specific panel of mycoplasma species is often crucial for providing insights into local mycoplasma epidemiology and updating clinical practice guidance.
Methods: We retrospectively reviewed reports of 4,166 female outpatients detected by the mycoplasma identification verification and antibiotic susceptibility kit from the last five years.
Results: Among them, > 73.3% of cases with Ureaplasma urealyticum or Mycoplasma hominis single infection or co-infection with both species were susceptible to three tetracyclines and one macrolide (josamycin). Additionally, > 84.8%, ≤ 4.4%, and ≤ 39.6% of the U. urealyticum, M. hominis, and co-infection cases, respectively, were susceptible to clarithromycin and roxithromycin. Four quinolones (ciprofloxacin, ofloxacin, sparfloxacin, and levofloxacin) and three macrolides (azithromycin, erythromycin, and acetylspiramycin) were active against < 48.9% of the isolates. Furthermore, 77.8%, 18.4%, and 7.5% of the M. hominis, U. urealyticum, and co-infection cases, respectively, were susceptible to spectinomycin.
Conclusions: Tetracyclines and josamycin were the best antibiotics for most mycoplasma-infected patients.
